Remove undocumented and uncontrollable WiFI RSSI filter. (espressif#5393)
Commit d15e1b0 [1] in the 2.0.0 pull request espressif#4996 introduced a filter to connect only to WiFi networks with a RSSI of -75 or better. This results in strage behaviour, as a scan still shows networks, that can't be connected to, even though with older versions, connecting to those networks was possible and the connection (albeit slow) was stable. Remove the RSSI filter for now by setting the threshold to -127, i.e. the lowest possible value. Maybe in the future the filter threshold could be exposed to users, to allow filtering out nearly unreachable networks. [1] github.com/espressif/pull/4996/commits/d15e1b0
